Treatment Options for Hiccups
For hiccups, treatment should follow a stepwise approach starting with physical maneuvers for acute cases, progressing to chlorpromazine (25-50 mg three times daily) as first-line medication for persistent cases, and considering alternative medications like baclofen, gabapentin, or metoclopramide for refractory cases. 1
Classification of Hiccups
Hiccups are classified based on duration:
- Acute: Less than 48 hours
- Persistent: More than 48 hours but less than 2 months
- Intractable: More than 2 months 1
Treatment Algorithm
Step 1: Physical Maneuvers (First-Line for Acute Hiccups)
For hiccups lasting less than 48 hours, try these techniques:
- Breath-holding
- Rapid water drinking
- Swallowing granulated sugar
- Pulling on the tongue
- Stimulating the uvula/pharynx
- Larson maneuver (suprasternal pressure) 1
These physical techniques work by disrupting the hiccup reflex arc and are recommended by multiple medical organizations as first-line treatment for acute hiccups.
Step 2: Pharmacological Treatment (For Persistent Hiccups)
If physical maneuvers fail or hiccups persist beyond 48 hours:
First-line medication:
- Chlorpromazine: 25 mg three times daily
- Can be increased to 50 mg three times daily if ineffective after 2-3 days 1, 2
The FDA-approved dosage for intractable hiccups is 25-50 mg three times daily or four times daily 2.
Alternative medications (if chlorpromazine is contraindicated or ineffective):
- Baclofen: Particularly for central causes of hiccups
- Gabapentin: Effective for neuropathic-related hiccups
- Metoclopramide: Useful for peripheral causes, especially GI-related hiccups 1, 3
Step 3: Advanced Interventions (For Intractable Hiccups)
For hiccups persisting beyond 2 months:
- IV chlorpromazine under careful monitoring
- Nerve blocks
- Nerve stimulation
- Acupuncture 1
Special Considerations
Underlying Causes
Always identify and treat underlying causes of persistent hiccups, which may include:
- Gastroesophageal reflux disease
- Myocardial ischemia
- Central nervous system disorders
- Medication side effects 1, 3
Monitoring and Precautions
When using chlorpromazine:
- Monitor for hypotension, sedation, and extrapyramidal symptoms
- Use lower doses in elderly, debilitated, or emaciated patients
- Be aware of QT prolongation risk, especially when combined with other QT-prolonging medications 1, 2
Common Pitfalls to Avoid
- Failure to identify underlying causes: Treating symptoms without addressing the root cause can lead to prolonged hiccups 1
- Overlooking drug interactions: Particularly with QT-prolonging medications when using chlorpromazine 1
- Using high doses in vulnerable populations: Elderly patients are more susceptible to adverse effects and require lower dosages 1, 2
- Premature escalation to pharmacotherapy: For acute hiccups, physical maneuvers should be tried first before moving to medications 1
While numerous treatments for hiccups have been reported over centuries, the evidence for many interventions remains limited. The stepped approach outlined above represents the most current guideline-based recommendations, with chlorpromazine having the strongest evidence and FDA approval specifically for intractable hiccups 1, 2, 3.
